What is the value of x? A.39 B.41 C.26 D.17

mojhsa [17]

Answer:

The answer is B.

Step-by-step explanation:

You have to use Pythogorean Theorem, c² = a² + b² where c is the hypotenuse and a,b is the side lengths :

${c}^{2} = {a}^{2} + {b}^{2}$

Let a = 40,

Let b = 9,

${c}^{2} = {40}^{2} + {9}^{2}$

${c}^{2} = 1600 + 81$

${c}^{2} = 1681$

$c = \sqrt{1681}$

$c = 41 \: units$

*Take note, hypotenuse will always be the longest length among the 3 lengths.

*Pythogorean Theorem can only applied in a right-angle triangle.

A circumscribed figure is inside another figure while an inscribed figure is outside another. True or false

12345 [234]

The term circumscribed means to limit, to restrain, or to surround. The figure circumscribed another figure means it is outside of that figure. On the other hand, the term inscribed means to draw the figure within another. This means that it should be inside another figure.

The given descriptions above are the exact opposite of the true meaning. Hence, the answer to this item is FALSE.

PLZ HELP SOON

Elanso [62]

13/8 = 1 5/8

Since 13/8 = 1 5/8, A and B cannot be correct.

5/8 > 1/2

Since 5/8 > 1/2, 13/8 is closer to 2 than to 1. Therefore, the answer is D. closer to 2 than to 1.
